There are many contents of food nutrition, including food hygiene, reasonable preparation, food processing, cooking, types, eating methods and habits. What is this? Come and have a look with me.

1, pay attention to food hygiene.

There are many contents of food hygiene, one of which is to prevent unclean diet. Animals, fish, shrimp, crabs and some aquatic plants can become intermediate hosts of some parasites, and food is easily polluted by various parasite eggs, cysts, pathogenic microorganisms and "three wastes" or residual pesticides produced in industrial production during processing, storage and transportation, so eating unclean food can often cause various gastrointestinal diseases, parasitic diseases, infectious diseases or poisoning. Second, don't eat spoiled food, and don't eat the meat of six kinds of animals that died from their own deaths or epidemics, so as to avoid "food poisoning". On various sources and symptoms of diseases

2. Promote moderate diet

In terms of diet nutrition, we advocate moderation, develop good eating habits, and advocate regular quantification to prevent hunger and satiety. It is believed that "with food, there will be no disaster in the body." Lu Chunqiu's food intake varies from person to person. If you overeat, it is easy to eat stagnation, damage gastrointestinal function, or cause other diseases; Long-term hunger will lead to the loss of viscera and the weakening of healthy qi, and it is also easy to cause the invasion of exogenous pathogens.

3. Overcome dietary prejudice

Overcoming dietary partiality is an important content of five flavors health preservation, which embodies the idea of balancing diet and advocating comprehensive and reasonable nutrition. Overcoming dietary prejudice mainly includes two aspects:

The first is to overcome the hot and cold diet. The diet is cold and easy to hurt the spleen and stomach yang; Long-term partial eclipse is spicy and warm, which is easy to cause gastrointestinal heat accumulation or aggravate hemorrhoids. Therefore, the requirement for eating habits is to be moderate in cold and temperature, eat less spicy and spicy food, and use it with caution when it is cold.

The second is to overcome the five flavors. The five flavors nourish the viscera, and each has its own affinity. If you indulge in a certain diet for a long time, it will easily lead to dysfunction of dirty qi or form a "paste beam" change; At the same time, it will lead to the lack of other nutrients, make the body lose nutrition, and thus produce various diseases. This is also the case, as pointed out in "Bao Sheng Lu Yao's Discussion on Diet Door": "A good thing should not be partial to food, and a partial food will hurt the disease; The bad smell is not abandoned, and if it is abandoned, it will be uneven. "

4, medicated diet health care

Medicinal diet is a delicious food with the functions of preventing and treating diseases and strengthening the body, which is made by combining food with drugs, food accessories and seasonings under the guidance of traditional Chinese medicine theory. Commonly used medicated diets include ginseng, Astragalus membranaceus, Polygonatum sibiricum, Cordyceps, Polygonum Multiflori Radix, Poria, Mulberry, Sesame, Walnut, Honey, Lotus Seed, Kiwi Fruit, Beef, Duck, Fish, etc. The main characteristics and application requirements of medicated diet include: combination of medicine and food, adaptation to the time, dialectical diet and so on. Practice shows that proper medicated diet, combining the advantages of medicine and food, can indeed receive health care, anti-aging and anti-aging effects, which is quite characteristic content in dietotherapy and health preservation.

Matters needing attention in diet health preservation

1. Comply with nature

With a natural time sequence, try to choose all kinds of natural plants. For Chinese medicine, nourishing liver and protecting eyes in spring, regulating blood in Changqing Xia, moistening dryness and nourishing qi in autumn and tonifying kidney in winter are all changes of nature and human body, so seasonal fruits and vegetables are selected to ensure natural health.

2. Don't be partial to food

Eating more foods containing six nutrients, such as carbohydrate, fat, protein, water, vitamins and minerals, and avoiding being limited to a few kinds of ingredients will not only hinder appetite, reduce nutrient intake, but also cause nutritional disorders. Vegetarians may have a tendency to rely too much on soy products, so try to diversify the types of ingredients and make them more creative.

3. Eat less foods high in sugar and fat.

It doesn't mean that if you don't eat animal fat and meat, you won't be obese and you can ensure the health of your heart and blood vessels. As long as you are a vegetarian with high fat and sugar, you will also have this drawback, which will also lead to high blood pressure, high cholesterol or high blood sugar. Therefore, we should eat less fried things and control the amount of oil used in cooking, such as gluten, baked bran and oil noodles. Foods with high oil content, such as, etc. Diet should be controlled to inhibit the accumulation of calories in the body and reduce the occurrence of chronic diseases and civilized diseases.

4. Add the right amount of protein.

Plant-based foods can't completely provide essential amino acids for human body. In order to meet the energy demand of human body, it is suggested that non-vegetarians should supplement foods containing complete protein, such as eggs, milk and dairy products. Vegetarians can supplement soybeans or other beans, as well as soybean milk, tofu and processed protein products to enhance their nutritional value. At the same time, if protein is burnt, it may turn into carcinogen, so pay more attention when cooking. ?
